Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511056, here are decompositions:

53 + 31511003 = 31511056
257 + 31510799 = 31511056
293 + 31510763 = 31511056
503 + 31510553 = 31511056
569 + 31510487 = 31511056
653 + 31510403 = 31511056
659 + 31510397 = 31511056
839 + 31510217 = 31511056

Showing the first eight; more decompositions exist.
